l. A valve comprising a valve body provided with a bore for communication with a source of liquid supply and having a tapered shoulder .within said bore; a relatively long non-metallic plug inserted in said bore andhaving one end enlarged to form a head adapted to rest on said shoulder, saidfplug being provided with an aperture4 therethrough; and a closure member having a `port for registry with said aperture the face on saidfplug head, nearest said closure member being tapered to engage the tapered shoulder in vksaid bore, said closure member being contacted Vmoved into and oui-,of registry with `said bore; a tapered shoulder within said bore between said closure member and the source of fluid supply; a relatively long cylindrical non-metallic plug mounted insaidl bore and having theperiphery atv one, end thereof enlarged to form a head with its annular face nearestA the control member tapered to engage said. tapered shoulder andprovided with anaperturey through `said plug and with vwhich the port of said control member is adapted to register; said plug being of pliable :material 4'that when "said control member is moved.

to closed position, the pressure of liquid from the source'of supplyv will urge said plug againstsaid member to form an effective liquid tight seal. BENGEMAN BEASON OWENS.
